TYPE-WRITING MACHINE.

Specification of Letters Patent.

Patented March 26, 1907.

Application filed October 22, 1902. Serial No. 128,287.

To all whom, it meaty concern:

Be it known that I, ROBIE SEIDELINGER, a citizen of the United States,and resident of Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented certain new and useful Improvements inType-Writing Machines, of which the following is a specification.

My invention relates to ribbon-feed mechanism for type-writing machines;and one of the main objects of the invention is to provide simple andeflicient mechanism of the character described for automaticallyreversing the direction of the feed of the ribbon when a given amountthereof is fed from one spool to another.

A further object of the invention is to pro vide simple and eflicientmechanism for automatically effecting a transverse as well as alongitudinal feed of the ribbon, so that every portion thereof may beused.

To the above and other ends, Which will hereinafter appear, my inventionconsists in the novel features of construction, arrangements of parts,and combinations of devices to be hereinafter described and claimed.

In the accompanying drawings, wherein like reference characters indicatecorresponding parts in the various views, Figure 1 is a vertical centralfront-to-rear sectional view of one form of type-writing machineembodying my invention. Fig. 2 is a transverse sectional view of thesame, the section being taken on the line :0 0c of Fig. 1 and looking inthe direc tion of the arrow at said line. Fig. 3 is a fragmentaryvertical front-to-rear sectional view of the machine, the section beingtaken on the line y y of Fig. 2 and looking in the direction of thearrow at said line. Fig. 4 is an enlarged detail fragmentary perspectiveview of a portion of the reversing mechanism to be hereinafterdescribed.

I have illustrated my invention applied to an under-strike type-writingmachine, though itshould be understood that for the purpose of myinvention it is immaterial what character of writing-machine myinvention is applied to.

The frame of the machine comprises a base 1, corner-posts 2, and a topplate 3, which latter supports a traverse-rod 4, that guides thecarriage 5, in which a platen 6 is mounted to revolve.

The rear of the carriage is provided with rollers 7, that cooperate withthe traverserod, whereas the front of the carriage carries alroller 8,that bears upon a track 9 of the top ate.

p Key-levers 10 are fulcrumed on a bar 11, projecting from the base 1,the forward end of each lever being provided with the usual finger-key12, and a connecting rod or link 13 is interposed between each key-leverand its associated type-bar 14, whereas a restoringspring 15 isassociated with each lever to assist in restoring it and the connectedparts to their normal positions.

A universal bar 16 extends transversely beneath the various key-leversand is connected at its ends to upright links or rods 17, that aresupported by their hooked ends on a transverse bar 18, connected to therockerarm 19, secured to a rock-shaft 20, that carries an uprightrocker-arm 21, provided with feed-dogs 22, which cooperate with thefeedrack 23, connected to the carriage. A spring 24 is connected at oneend to the rock-shaft 20, and at its other end bears upon a fixedbracket-plate 25, so that the tension of the spring is exerted torestore the rock-shaft and the parts connected thereto to the positionshown in Fig. 1. The carriage is connected by a band to a spring-drum,so as to move the carriage a letter-space distance in the direction ofits feed at each actuation of a finger-key.

So much of the mechanism as has thus far been described constitutesportions of a wellknown type-writing machine, and further detaildescription thereof is considered unnecessar A The ribbon 27 passes froma ribbon-spool 29 at one side of the machine to a ribbonspool 30 at theother side thereof, whereas the intermediate length of ribbon betweenthe spools passes through slots in the top plate, over the top plate andtype-well of the machine, and between the types and the platen in theusual manner.

Each of the ribbon-spools 29 and 30 is splined upon an associatedribbon-spool shaft 31, which extends fore and aft of the machine and issupported in bearings 32, depending from the top plate of the machine,so that each spool is free to move longitudinally on its shaft, but byreason of the splined connection therewith is caused to rotate with itsshaft. Each shaft 31 extends rearwardly of the rear bearing 32 thereforand is provided with a pulley 33 and a bevelgear 34, both of which arefixed to the shaft.

A driving-shaft 35 extends transversely of the machine and carriesbevel-pinions 36 and 37 at the ends thereof, and the length of thisshaft is such that when one of the pinions thereon is in mesh with itsassociated bevelgear 34 the opposite pinion on the shaft will be out ofmesh with its associated bevel-gear, as represented in Fig. 2. The shaft35 is supported in bearings 38 and 38*, that depend from the top plateof the machine and in which the shaft is adapted to slidelongitudinally. The bearing 38 is bifurcated for the reception of abevel-gear 39, which is mounted on the shaft and has a pin 40 thatextends through a collar on the gear and into a splined groove 41 in theshaft, so that this gear is adapted to remain fixed with relation to thelongitudinal movement of the shaft 35, but is connected to rotatetherewith. The bevel-gear 39 has peripheral ratchetteeth 42, with whicha spring-detent 43 cooperates, the detent being secured by a screw 44 tothe bearing 38, thus preventing a backward rotation of thedriving-shaft. The bevelgear 39 meshes with a companion beveldriving-gear 45, which is secured. to or forms part of a ratchet-wheel46, that is mounted on the same center as the spring-drum 47. Thespring-drum has a pawl 48 pivoted thereto at 49, and thenose of the pawlis maintained in engagement with the teeth of the ratchet-wheel 46 by aspring 50, that is secured to the pawl and bears at its free end againsta pin 51, carried by the drum. The drum 47 has secured thereto at 52 oneend of a band 53, the other end of said band being secured to thecarriage at 54, so that the tension of the spring is exerted. to effectastepby-step feed movement of the carriage during the actuation of thekey-levers.

An angular bracket 55 is secured by a screw 56 to the base 1 of themachine, and the upright arm of the bracket receives a headedscrew-pivot 57 of an upright lever 58, the upper end of said lever beingreceived within a peripheral groove or depression. 59 in thedriving-shaft 35, whereas the lower end of said lever carries alaterally-projecting pin 60, that is received within an aperturedportion 61 of a frame or lever 62, the latter being pivoted at 63 to anauxiliary bracket 64, that is secured by screws 65 to the angularbracket 55. The upper portion of the frame 62 is in the form of a yoke,the two arms 66 of which are apertured at diametrically opposite points,as indicated at 67, (see Fig. 1,) and these apertures receive a band,cord, chain, or ligament 68, which extends freely therethrough and eachend of which is secured to one of the pulleys 33. I prefer to make thepart 68 in the form of a fine chain or other flexible ligament in whichthere is little give or stretch, though it should be understood that anysuitable flexible connection may be used, and the term band employed inthe claims is intended to designate generically any suitable ligament,whether it he a chain, cord, or other line connection.

Secured by a screw 69 to the rear side of the upright arm of the bracket55 is a spring 70, which is bent at its free end 71 for cooperat'ionwith a cam 72 on the rear face of the lever 58. The purpose of thisspring and its cooperating cam is to insure a complete movement of thelever 58 and the parts eontrolled thereby when the cam is moved toeither side of the terminal 71 of the spring 70. The spring will whenthe highest por tion of the cam passes its end. 71 bearupon a side ofthe cam and assist or insur a complete movement of the lever and willlikewise quicken the action of the parts, as will hereinafter moreclearly appear.

The groove 59 in the shaft 35 is wider than the end of the lever 58.When the abutment 87 first engages an arm 66, the lever 58 is moved acertain distance without moving the shaft 35 at all while the end 71 ofthe spring 7 is riding upward on one of the faces of the cam 72. Whensaid end 71 of the spring passes over the top of the cam 72, said springcompletes the motion of the lever 58 quickly, thus instantaneouslythrowing one of the pinions 36 or 37 out of engagement with its gear 34and the other of said pinions into engagement with. its gear 34.

The driving-shaft 35 carries an eccentric 73, which. is provided with acollar 7 4, through which. a set-screw 75 projects, the end of saidset-screw bearing against the driving-shaft to rigidly connect theeccentric thereto. A strap 76 surrounds the eecentric and has adepending link 77, the lower end of which is pivoted at 78 to acrank-arm 79, that projects rearwardly from a rock-shaft 80, thatextends transversely of the machine and is seated in suitable bearingsin the sides of the base.

Projecting upwardly from the rock-shaft 80, near each end thereof, is acrank-arm :4 pivoted at its upper end 82 to a link 83, that in turn ispivoted at 84 to a yoke 85, the side arms 86 of said yoke passing on theouter sides of the flanges of the associated. ribbon-spool a'ndbeingperforated at the upper ends, where they are received on the associatedribbonspool shaft 31. It will be understood that the connection on bothsides of the machine between the ribbon-spools and the rockshaft are thesame, so that a rocking of the shaft 80 will cause both spools to bemoved axially or along their shafts 31 to a. corresponding extent toeffect a widthwise or transverse feed of the ribbon.

From the foregoing description it will be lOO seen, especially byreference to Fig. 2, that a movement of the carriage 5 from left toright will merely result in turnin the springdrum 47 withouttransmitting motion to the ratchet-wheel 46, and every portion of theribbon mechanism will at this time remain in a state of rest. When,however, the carriage is fed in the usual manner from right to left,motion will be transmitted by the spring-drum through the pawl 48 to theratchet-wheel 46. The eflect of this movement is to turn the bevel ordriving gear 45, thus rotating its associated pinion 39 and transmittinga rotary motion to the drivingshaft 35. This rotation of thedriving-shaft will turn the bevel-gear 34, with which. the pinion 36 or37 is in mesh, the pinion in mesh depending on the longitudinal positionof the driving-shaft. If, for instance, the pinion 37 is in mesh withits companion bevel-gear 34, then the left-hand ribbon-spool will bepositively driven by the rock-shaft, and the ribbon 27 will be moved inthe direction of the arrows adjacent to the ribbon in Fig. 2, and thevarious parts will be disposed as shown in said figure. The continuedrotation of the left-hand ribbon-spool shaft 31 will continue until anabutment 87 to the right of the frame 62 is brought to bear against theright-hand arm 66 of said frame, when the frame Will be shifted aroundits pivot 63 toward the left. This movement is transmitted through thepin-and-slot connection 60 61 to the lever 58, the upper end of which isvibrated toward the right, thereby moving the driving-shaft 35longitudinally toward the right until the pinion 36 thereon is throwninto mesh with the companion bevel-gear 34 of the right-handribhon-spool. This movement of the shaft 35 effects a disengagement ofthe pinion 37 from the gear of the lefthand ribbon-spool, and it becomesdisconnected from the drivingshaft, and the reversal in the longitudinaldirection of the feed of the ribbon is thus brought about. The ribboncontinues to wind on the right-hand ribbon-spool until the knot orabutment 87 on the band 68 is brought into contact with the left-handarm or frame 62, and a continued movement of the band results in theframe being shifted toward the right around its pivot 63 to the positionindicated in Fig. 2, which shows the positions of the parts just afterthe driving-shaft has been moved to the left. This movement istransmitted to the lever 58 to eflect a longitudinal movement of thedrivingshaft 35, so as to disengage the pinion 36 from the gear of therighthand spool and to throw the pinion 37 on said shaft into mesh withthe gear of the left-hand ribbon-spool, and so on, this action isrepeated to automatically reverse the direction of longitu of the band68 passes from one pulley to the other.

Upon reference to Fig. 2 it will be seen that the core a of eachribbon-spool, which is shown in dotted lines, is much larger than thecore I) of the pulley, which is likewise shown in dotted lines in thisfigure. It follows, therefore, that the surface speed of the core of theribbon-spool is much greater than that of the pulley, though eachassociated pulley and ribbon-spool are mounted on the same shaft androtate together. This construction permits a ribbon of any desiredlength to be employed and at the same time enables a comparatively shortextent of band 68 to be used. Thus, for instance, a ribbon of, say, fiveyards or more in length may be employed, whereas the band may be lessthan a yard in length, and by making the abutments 87 adjustable on theband an automatic reversal in the longitudinal feed of the ribbon can beeffected at any desired point in the movement thereof or at any predetermined point from the end of the ribbon. These abutments 87 may beof any desired construction such, for instance, as a mere split ringwhich is clamped in place upon the band. It will be-understood,therefore, that the machine may accommodate any desired length ofribbon, and by properly setting the stops or abutments 87 the directionof feed of the ribbon may be changed automatically as an end thereof isapproached. It will likewise be seen that by this construction there isno strain whatever exerted upon the ribbon itself to effect a reversalin the direction of its feed, that the mechanism for auto maticallyeffecting a change in the feed is brought about by mechanism which isentirely independent of the ribbon and which is actuated by the poweremployed to propel the carriage. Thus, for instance, the spring drumtransmits motion to the pulleys, and the band as it is taken up by onepulley will eventually cause the abutment on the band to be brought intocontact with the shifting device 62, thereby changing the longitudinalposition of the driving-shaft 35 and throwing it out of operativeconnection with one ribbon-spool and into operative connection with theother.

Upon reference to Fig. 2 it will be seen that the pivotal connection 78between the crank-arm 79 and the link 77 is such that the eccentric 73,strap 7 6, and link 77 maybe moved with the shaft during thelongitudinal movement thereof without in any way affecting the operationof the connections between IIO the driving-shaft 35 and the rock-shaft80.

The intermittent rotation transmitted to the driving-shaft 35 during thefeed movement of the carriage causes the eccentrics 73 to effect anintermittent vibration of the rock-shaft dinal feed of the ribbon when agiven extent l 80 in opposite directions, so that the cranknubarms 81are moved step by step first toward the front and then toward the rearof the machine, and these movements of the crankarms are transmitted tothe yokes S5 to cause the ribbon-spools to be moved longitudinally ontheir shafts 31, so that during an actuation of the machine the ribbonwill be automatically-fed widthwise, as well as longitudinally, andautomatically reversed in both directions to use the entire surface 01the ribbon.

Various changes may be made without departing from the spirit of myinvention, and certain features may be employed. without the others.
